Application filed July 12| 1889. Serial No. 317.369.

To'all {uhom 'it may concern:-

Be it known that I, FELIX BENEDICT HERoG, Ph D ',-a citizen ofthe United States, and a resident of thecity, county, and State of New York, have iny veniE'a new and useiul improvement in Electric Signaling Apparatus, of which theA following is a speciication.

' y invention relates to a circuit closer, which when closed, will .produce changes Yin the normal circuit conditions at its station, which changes will continue intil some act is performed at a distant point.

Referring to the drawings such a circuit. closer isV shown in connection with the complete circuit and apparatus at the distant station. Y

' In the form chosen 4for illustration, an armature isl erate with a suitable crcuitterminal to close the main net, at the operated station and at other points on the line are located the sources of current,-a suitable indi- Reierring to the drawing,` K representsa push the armature on its fulrum so as to vbring 'the contactv and 'theA pin carried by it against the contact point The circuit thus produced leads i from battery L, through suitable alarm D, through suitable key l,

that the circuit will remain closed until it is momenis broken. Normally, the armature will make con-4r tact with T andthe earth return, being thus held by its spring.

The mechanism so far described is fully effective, and for manypurposes is complete, butlvproduce additional results of value by combining this appara? tus with means whereby another circuit or part of circuit is rendered operative in the normal condition and positionV ot the armature. This may be vdone in various ways, and as shown herein, there is aback contact T c, which leads to a branch within which is another magnet Ic, adapted topproduce any .desired 4reearth brauch at the distant station. The magnet 1c is obviously operated when the key at theY distant station is moved'om its normal contact to the abnormal contact, which throws in the second battery arid the return'.

There are many modifications which I'have shownl in the present application as originally iled and va-A rious other applications, andjl do not wishto confine myself to the form shown herein, excepting. to the extent that the movement of the armature isat the rst step controlled mechanically as the direct result oi the push. -i

1. A circuit controlling device comprising`cireuit terminals, arranged and adapted tolbelbrought into contact after an armature has begun 'to be moved mechanically from its normal position of rest, together with this 'arma ture a magnet coperating with this armature to continue the change in the circuit conditions established as the result of such contact; means'gunder the control oi! an operator for moving the armature' mechanically away from its normal position of rest; meansgi'ncluding a. suitable lsource of current and connection, by, -which the current is epabled to iiow through both the magnet and the said terminals only after' the arm-attire has been moved mechanically, as described; and means controlled from a distant point and lcoperating to restore these parts.

2. At Va `signaling station a circuit controller which when' operated at will-by anvoperator thereat causes the.

3. At a signaling station a circuit controller which,

when operated at will by an, operator causes the armature of 'an electro-magnet to be moved; means whereby such movement changes 'the course of one orA more neighboring operation the establishment .of a circuit closed `through. the magnet, and remaining closed until ,some subsequent operation at the distant connected station; togethery with means for' re-opening such`closure independently of subsequent act b'y the signaling operator.. 4. In comblnation'with two lines in parallel from parts of the circuit to a distant station, including in itst sub-'station to a central station, a circuit closing deviceat l the sub-station signaling station, adapted and arrangedV "to produce -a circuit .changewhich sends an alarm to the .central station; means for continuing this circuit change -without Afurther action on the part of the operator, and a magnet at the sub-station controllable-'from the .central station only'after the signal has been received thereat and operating to restore the normal conditions, substantially as described.

5, At' one station e signaling instrument including terminals to a circuit leading to a distant station; means for joining these and thereby giving the signal, a magnet` 'coperating in `this operation, and an armature for the magnet constructedand arranged `to be moved mechanic ally during the operation of giving the signal. l

6. In signaling apparatus thea'rmature of an electromagnet coperating with contact points to act as a' top or' abnormal contact, and devices at a second station wherebyv the normal condition is restored;

scribed.

substantially' as de- 7. In a ll box telegraph, a call answering signal, an electro-magnet normally denergized vbut energized when said answering signalis movedto inoperative position, and adapted to hold said signal inoperative and to release said signal when said mgnet is denergized, and means fon moving said signal to inoperativ'eposltion by the sende iWe, the witnesses referred to, signour names on the gned in the same date.
